Lady Gaga is auctioning off a tea cup she drank from during a press conference last year (11) to raise funds for artists in Japan following the country's devastating earthquake and tsunami.

The Poker Face superstar has put the ceramic blue and white cup under the hammer via Yahoo! Japan auctions in a bid to raise big donations for a program which supports young Japanese artists who want to hone their craft abroad.

Lady Gaga sipped from the cup during a press conference to announce a benefit concert last June (11) to support the country's efforts to rebuild areas ravaged by the natural disasters which hit the country in early 2011.

As WENN went to press, the bids had reached over $80,000. The auction ends on 6 May (12).
